Although this is somewhat unrelated, I just want to comment here that
OpenLayers provides a non-tile based client side vector map renderer as
well. Although it is not likely to be optimized for the same use case as
this is, I wanted to make anyone who cared aware that this type of
functionality has been in OpenLayers (and steadily improving in many
ways) for multiple years now.

Included is:

 * The Ability to read many different goedata formats (KML, GeoRSS,
   GeoJSON, WKT)
 * The ability to render in Canvas, SVG, or VML
 * THe ability to interact with drawn features -- click to select,
   change color on hover, etc.
 * THe ability to draw in the map, adding new data,
 * Styling based on SLD, or Javascript-generated style descriptions 
   in a simlar vein to SVG.
 * etc. etc.

Best Regards,
